M18x Memory Discussion Thread

When I was shopping for ram, I also wanted to find CAS 7 stuff at 1600mhz but couldnt find anyone who did it in the size sticks I wanted. From recollection, I think 2x2gb was the biggest kit I saw but obviously, not much use.....

 

The only other option would be to buy the 1800 stuff, down clock it too 1600mhz and then push for as tight timing as poss. Anyone on here tried that with 204-pin, if so what have lowest they've managed to get cas wise?

 

Has anyone with 2630QM tried the 1600Mhz memory yet?

 

According to Intel, doesnt it only support max 1333?

 

Intel is not always spot on. Sager owners report that it in fact works at 1600 MHz. I have yet to see it with my own eyes though. Anyway, since I'm gonna upgrade the CPU down the road, might as well grab HyperX now.

 

Yeah, I heard that too.....for the small price difference, even if it does get downclocked, its a no brainer, IMHO.

 

Has anyone tried OC'ing the 1600MHz RAM to 1866?

 

Does the M18x bios allow for timing adjustments? I would love to test my HyperX 1600 at 8-8-8-24 or 7-7-7-21

 

Sorry for the dummiest question but... are those Kingston HyperX (1600 and 1866) PnP double chanel or triple chanel?
and... why the 1886 has CL11 and the 1600 CL9?
There is a so big variety that's like mandarin for me...

 

They're dual channel. Triple channel memory only works on the X58 chipset with the original core i7 desktop chips as far as I know.
As for the timings, they tend to be more 'loose' as the speed increases. Price/performance wise, the 1600 would be a nice happy medium. Higher timings mean larger latency, but the performance differences are generally negligible.

 

Thanks pal! I got it

 

Any comments on this link?

 

Seems a very appealing improvement. Less energy=less heat. It will be interesting what's the Micron / Kingston anwers...

 

I received my M18x the other day I have installed the Kingston PnP memory but it shows that it is only running at 800mhz, is there something I have to change in the Bios to get it running at 1600mhz?

 

Its Dual Channel mate, so 800mhz x2 = 1600mhz....... - nothing special you should have to do!

 

lol I never thought of that thanks.

I do have the i7 2630qm cpu so then yes the system does see the memory at 1600mhz.

 

No worries mate.


Well thats good news as Intel only list your cpu as supporting 1333.....great if the kingston is running at 1600mhz instead! - happy days!

 

Great news! Gonna order a couple of sticks then.

 

wow then i guess itll also support 1866mhz. i wonder if its just in "overclocked" mode.

 

You should be able to just set the XMP profile to 1866 and leave everything else alone.

 

Be careful with the Kingston rebate. Kingston has a $30 rebate on their non plug and play 4G x 4G packages of 1600Mb RAM. Now you can get it for $75 after the rebate. The non plug and play works great for me.

I recommended calling Kingston while you are filling out the form to make sure you are conforming to their requirements. An order confirmation or packing slip isn't enough. I bought mine from Buy.com and Kingston requires a copy of the purchase history.

If you buy two packages for twice the rebate, on their form Kingston says you have to put both UPC codes in the same envelope. You also have to fill out two complete applications and include two copies of the purchase history. That isn't mentioned on the form.

 

Maybe I don't quite understand: Is it valuable at all to install 1866 instead of 1600 when the latency in the 1866 is 11 and in the 1600 is 9?

Thanks for any educated (and educational) answer for a dummy...

 

DDR3-1600 vs 1866
I hope this helps. They'll trade blows for the most part. I went with the 1600 as the price difference didn't justify much of a performance gain.

I have yet to play with my timings, but you may be able to get the 1866 ram down to cas 9 or even 8 with some tweaking. Perhaps Scook could assist you with this. I'm pretty sure he has the 1866 PnP kingston ram.

 

Ok, I pulled the trigger and ordered 2x4GB 1866 from Newegg.ca. It's only 123$, 10$ above the 1600 one but the 1600mhz is temporary out of stock so there was really no question. Will see how it works with 2630qm.

 

Heck, for the price difference, I would have ordered them even if the 1600 ones were in stock.....nice buy.

 

different architecture, sandy bridge wont have those large gains

 

Wow, placed my order 3 hours ago and it has already shipped, hehe. Newegg FTW!

 

didnt your order consist of 8gb 1333? if so, let me know the difference. 3dmark 06 should go up 100 points.

 

yup, my system came with 8gb 1333. Hopefully I can see some improvement. Also interesting to see if the temps are affected.

 

most improvements come with a sandy bridge past 4ghz : /

 

Will get to it eventually but for now I'm curious if there's any benefit in 1866mhz paired with a 2630QM.

 

Does anybody knows what "Auto Self Refresh" Memory Module Feature is (Everest)?
I replaced 4G Hynix default memory with HyperX@1600 PnP but the above "Auto Self Refresh" Feature is not available anymore acording to Everest.
Windows Experience Index score for Memory went up from 7.6 to 7.8

 

I'm confused by the -plugnplay- aspect of the gray 1600mhz dimms ( Newegg.com - Kingston HyperX 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1600 HyperX Plug n Play Laptop Memory Model KHX1600C9S3P1K2/8G)

Does that mean that I need to set my xmp profile to 2 or just leave it alone?

 

I think the "plug n play" aspect is simply to state that you install it and forget about it. I dont think there is a requirement to enter bios and select an xmp profile. Maybe someone who has these could verify this.

 

Aik I would really like to hear from you on this ... my system is on a truck !!! Time to order new ram, and SSD and Bigfoot Killer ! But I want to know about the RAM asap !

 

I think it automatically makes the adjustment. Here is a screenie from CPU-z.

 

Sounds about right....I dont have the plug and play ones...I have the Blue ones.....if i dont set xmp, its not 1600 (i will check)......if you get that without changing anything in bios, its good to go.....afaik.

 

Has anyone had problems adjusting their memory timings with a custom xmp profile? Every time i change it, (7-7-7-21/8-8-8-24 etc) it shows in windows as running at 13-9-11-32. Either windows is wrong, or dellienware put out yet another fine pile of crap for an A00 bios. Hopefully that's not the case.... i can't take 5 months of "we're looking into that issue" just to receive a BIOS update that breaks something else on the laptop.

 

Anyone know when the 2133Mhz memory is coming out?

 

I've been running the 8GB@1866MHz paired with 2630QM for the past 2.5 weeks with zero issues. The RAM is plug&Play, no profiles selection necessary. Totally loving it!

 

Here is some RAM reading I just happen upon.
Kingston HyperX 8GB 1866MHz PnP Memory Kit For Notebooks - Sandy Bridge Notebooks Get HyperX Treatment - Legit Reviews

Oh by the way........
This RAM placed my windows score at 7.9
Aikimox, what did it post on your machine?

 

I'd be surprised if anything like that came out for notebooks, ddr3 1600 and 1866 are both overkill.

Most likely ddr4 will have those speeds but ddr4 is point to point so it will be a while before we see anything implement it. (2012/2013?)

 

Well I was doing some reading and some people seem to believe the 2133Mhz RAM will be coming out soon. Just seeing if anyone knows anything definitive. This is just more curiosity on my part. =)

 

It's been a while since I messed with this, but I'm pretty sure that what you "want" is to set the timings manually, and that by selecting a XMP "profile" you are overriding anything you set manually with what the profile is set for. Maybe I'm wrong but that's what I recall.

 

The only way I'm seeing to adjust memory timings is by using the XMP profile option and selecting "Custom"

 

Does that work properly for you?

 

No the timings are displayed as some off the wall timings like 13-9-11-32 and no matter what they are changed to, it takes no effect.

 

So is ALL the 4/8/16GB 1333MHz/1600MHz stock memory from Hynix, or are there any other brands that have shown up?

 

Ive had a mixture of Dell stock ram before now. On one rig which had 6gb, they threw in a 4gb Hynix module and a 2gb Kingston module (which would have been value ram not HyperX).....least I think it was Kingston....def. two different manufacturers though as I recall thinking it was odd....hey ho!

 

Wondering the same thing. I have yet to order the ram in my sig because I was waiting for this.
